IMPROVEMENT IN LIOOMS FOR CIRCULAR WEAVING.

Specification forming part of Letters Patent No. 72,362, dated December17, 1867.

To all whom it may concern:

Be it known that I, JOHN BUsER, of the city and State of New York, haveinvented, made, and applied to use a certain new and useful Improvementin Loom-s for Weaving Cylindrical Articles; and I do hereby declare thefollowing to be a full, clear, and exact description of the saidinventionreference being had to the annexed drawing, making partof thisspecification, whereinf Figure l is a plan of the machine, with thguide-roller over which the cord passes removed. Fig. 2 is an elevation,the frame being removed at the line .r a'. Fig. 3 is a sectional plan atthe line fr fc. Fig. 4 is a similar plan at the line y y and Fig. 5 is asectional plan below the line y y', Fig. 2.

Similar marks of reference denote the same parts.

The object of my invention is to weave a covering for shade-cord, or toAweave any character of circular covering or cylindrical articles, andsaid invention consists in a series of warp-movers standing radially, incombination with a shuttle revolving around the article being formed. Ialso make use of a peculiar stop-motion that prevents a further movementof the parts when'either a warp-thread or the shuttle-thread breaks. l Y

In thedrawing, a a are the frames of the machine, of suitable size andcharacter. b is a table, upon which the warp-spools c c are placed, andkept from turning too freely by .,a cord, l and spring 2, acting on thegrooved pulleys of the spools, or in any other convenient manner. 3 3are guide-wires, between which the threads from the warp-spools c passto the friction-rollers d d, kept together by a spring, 24, and thefriction regulates the tension of the warps. I cover one or both of therollers d with felt or other elastic material, so as to give a betterhold upon each of the warp-threads. The warps pass below the guideroller or drum d', and up through eyes at the ends of arms e e. Thesearms are hinged at their lower ends 4 to the bed-block al, and standradially around a center shaft, j', running upward and outward. Thethreads, drawing in toward the weavingpoint 6, hold these larms c up;but in case of any warp being loose its arm moves sufficiently to takeup the slack. If thread breaks, its arm @falls and strikes upon one ofthe levers g, projectin g from the shaft g or g2, giving the same apartial rotation. 7 is a lever on the shaft g?, acting upon a lever, 8,on the shaft g1, so as to communicate motion from one to the other. Fromthe shaft g1 a link, 9, connects with a latch, l1., upon theclutch-lever h', so that when either of the shafts g1 or g2 is turnedthe latch h. is raised so as to be acted upon by a piu, 10, projectingdown from the under side of the cam l, and press back the latch t', thatholds up the clutch-lever h', and allow its spring ll to draw down theouter end of said lever, and lift the coupling or clutch k fromconnection with the pinion l1, and thereby stop the rotation of themachine if a thread breaks. The pinion Z1 isto be driven by the pinionl2 on the shaft 12,. or in any desired manner. The clutch-lever h has aprojecting handle, by means of which it may be raised to connect thepower, and held up by the latch i. The bed a2 is provided with forkedbearings around its ed ges for the warp-movinglevers m m. Each of theseis provided with a curved warp-mover, n, with an eye at its inner end.These levers m m are connected across by wires 13, so that motion onlyhas to be given to one of the 1evers in each pair. The warp-threads passfrom the eyeson e e through the eyes on n up to the point of weaving, 6,and the warp-movers n being changed each passage of the shuttle, theweaving is performed of the usual character, the shuttle or shuttlesbeing driven around in a circular raceway in the bed o', as hereafterset forth, and, passing between the warps, de-

posit the weft-thread, and the bed o is slotted radially to allow forthe play of the warps.

The levers m are moved at the proper time by the cams Z and Z4 actingupon rollers at the ends of arms p p, swinging upon fulcrum-studs 15,and connected by links 16 to the said levers m.

'I he shaft f extends up to the gear q, that drives the gears q1 andshafts 17, which have their journals in the beds a2 and 0.', and carryat their upper ends gears g3, (shown by dotted lines in Fig. 1,)whivchact upon teeth in the base of the shuttle-frame o, to propel the samearound in its circular raceway in'o, the gears g3 all traveling in thesame direction, and being placed so that one gear takes the teeth on theshuttle-base before the previous gear ceases to act on the same. Where acord is covered, the said cord is supplied from a reel, r, with aspring-friction, and the same passes up through a tube, 1^', in thecenter of the bed 0 thence to the point of weaving, 6. Theshuttle-frames taper toward the same point, and the wefttliread is ledoif through a hole at the apex.

The bobbin s in the shuttle-frame o has a spring-friction, s', appliedthereto, and the weft-thread leads behind the spring-bow axis 18 and infront of the spring-bow 19, so that when the weft-thread is in place thespringbow 19 is inside the shuttleframe o; but if said thread runs outor breaks, a little spring coiled inside the frame o turns the bow 19out, and in the revolution of the shuttle this bow 19 eomesinto contactwith a lever, t, on a fulerum, 20, and the other end of the lever tpresses a bar, t1, aside, so that it is no longer supported by a'notchin its side, taking the plate 21, and falls. The bar t1 has an arm, t2,

that, coming` into contact with one of the levers g, moves that and theshafts g1 and g2, and causes the disconnection of the clutch h and thestopping of the machine.

The material as it is woven is drawn away by the barrels u and e, actedupon by the worin-pinion e and wheel u', to the barrel a, and thematerial is coiled on a spool or reel, w, set in a swinging` frame, lw',and driven by a belt, 23. A spring, x, added to the weight of the spoolw and frame, causes sufcient friction of the belt 23 to turn the spool was the woven article is supplied to it.

This machine may be fitted to weave with any desired number of warps bymultiplying the parts.

What I claim, and desire to secure by Letters Patent, is

1. A series of warp-movers acting radially and moved by the mechanismshown, in combination with a shuttle revolved between the warp-threadsby the gearing, arranged and operating as set forth. p

2. The arms e, in combination with the shafts gl g2 and disengagingmechanism for stopping the machine it' a warp-thread breaks,substantially as set forth.

3. The bow 19, applied in the shuttles, in combination with the disengaging mechanism, substantially as set forth.

In witness whereof I have hereunto set my signature this 6th day of May,A. D. 1867.

JOHN BUSER.
